Abstract (en)
The invention relates to an apparatus (1) for testing tyre compounds, which comprises a road drum (3) and a specimen (5), rotating about respective parallel axes (X, Y) and being in rolling contact with each other. The specimen (5) of rubber to be analysed is mounted at the end of a spindle operated by a motor (6): advantageously the spindle is housed inside a closed casing (63) so as not to be exposed to water or other agents during the tests. This results in an apparatus wherein the spindle driving the specimen may be supported by non-sealed and hence low-friction bearings, thereby not altering the results of the tests carried out. <IMAGE>
